This is just a simple code, I use separate variable because I get them from different utilities such as a result of grep or sed and psql

Which shell are you using?

I am using bash, for example I have something like that

var1 = $(grep....
var2 = $(psql

And I want to merge it together

How about
Code:
var4=$(printf "%s\n%s" $var1 $var2)

var3=$var1$LF$var2
